No. If under “it” you meant a network adapter then here is a continue of the story.
I found that with the Tp-Link AC600 redline recommended adapter the Linux kernel produces quite a bit of error messages:
[ 623.876567] brcmfmac: brcmf_set_channel: set chanspec 0x100c fail, reason -52
21 message right after start:
$ dmesg | grep “reason -52” | wc -l
21
These messages keep coming with some regularity.
So what I did is I removed AC600 and switched back to the internal adapter. With the internal one I do not see any Linux kernel errors. Generally the internal adapter seems to be more stable.
I never had a problem of a weak signal with the internal adapter (at least how UI shows it). The idea of using an external adapter was coming from 1F support when I asked about a problem of not restoring a wifi connection after reboot. It turned out that this problem is here regardless what adapter is used.
While experimenting with the external adapter I also removed grounding of HMI as redline support suggested but I am not sure if it is relevant to network connectivity.
My routine now is as follows:
- use the internal adapter
- switch on the machine
- wait for not less than 1 min
- go to the config->network tab and click “test”. After about 15-20 sec I usually get HMI connected.
During working days I do not use the machine much so I have not collected enough statistics yet. But this is my current stand.
